Donie's place was the perfect home away from home with everything you might need for a longer term stay (I stayed here for 5 weeks). The apartment feels cozy and homey, with a beautiful view over the Onnut area from the balcony.
The neighborhood has many restaurants and shops around, but if you don't feel like going out and want to enjoy the AC, you can get anything easily delivered. The closest BTS station is 10-15 minutes easy walk away.
Donie and Christoph are great hosts and always available to answer any questions you might have, including giving plenty of tips on what to do and where to go in Bangkok.
In summary, book it :)
